drm/amd/display: Set flip pending for pipe split
[WHY]
When doing split pipe, if one pipe is pending on flip, the entire
plane's status should be flip pending, otherwise corruption can occur
when OS writes to a surface prematurely.
[HOW]
Clear the flip pending bit before checking pipes, then OR the flip
pending bits from all pipes together to create the flip pending status
of the entire plane.
